I think my warranty is up in two months, hence the sudden interest in putting a smaller pulley on

I have been doing a lot of searching, and have sent a few pm's to some members requesting sizing. Found people using 9, 9.5, 11psi with apparently standard ts2+ tune. None of the posts state the diameter of the pulley though Also found someone using a 13psi but with piggy back and 1mm head gasket.

Curiosity got the better of me, just measured up my TS2+ pulley, as supplied by ESS and it is 83mm, although I bought the TS2+ Upgrade kit that specifies the 81mm pulley. Disappointed. If I had known there were two different '81mm' pulleys, I would have requested the one that measures 81mm.

Just buy the 60 mm pulley and aftermarket ECU.....

M54B30 on 98, standard engine. (conservative tune)

I think that will be the end goal, I have enquired with ESS for the TS3 but they never reply, probably because I have the non m smg/ ssg. The reason for this post in the first place was to get some info to hopefully push the kit a little further till I rebuild and strengthen the bottom end in around 12 months time. I did email ESS to see if they had a further upgrade at all, but again, no response, not even a 'no we don't'. There kit is excellent, I can't complain with it at all, but it is disappointing when you have paid $9400 au for a TS2+ system ( $8800usd ), find you have been given a pulley different to what they advertise, and won't reply to a few simple questions

I have the ts2 pulley spare, I will chuck it on the lathe in the next few days, I am thinking 78-79mm.

At one stage I think ESS down sized there boost while maintaining same power levels using a different tune for the lower boost.
Eg: From 81mm to 83mm for the TS2+. (same horse power, different tune)

Yeah, seems you are correct, they just haven't ever updated their website

I have spent my free time over the last few days reading all the posts by ess on this forum looking for info. Seems they made the change because our engines are ageing.

I will be interested to put it back on the dyno after exhaust and pulley, should do a lot better (fingers crossed) on a cooler day, also read that the ess tune retards the ignition timing above 30 degrees Celsius, last dyno was 320whp (dyno dynamics) in 37 degree heat, and badly heat soaked.

Can anybody confirm what a 9.5psi pulley diameter would be?

9.5psi would be around 77mm.

Yeah from what I read they traded up pulley size and ran more timing down low.
Safer for the engine overall, but didnt change overall output.

So its possible to have a TS2 with 85mm or 83mm and TS2+ with 83mm or 81mm.

Also from what i could gather the TS2+ made most of its gains via cams anyway. 0.5 psi can't account for that much of a difference.

with the ESS 83mm from my TS2+ I can get 9.6psi of boost in 4 gear....

If you have plugged into the supplied manifold vacuum lines, your will not be running 9.6psi. There is a drop in pressure as the air passes over the laminova cores and cools. For an accurate reading, you would have to drill and tap post laminova's in the manifold.

This is going to make it very confusing to update the first post

Thanks cosmos328Ci, I will keep mine conservative at 78-79mm for a trial.

oh!!!! well I put the vacuum hose in the supplied manifold vacuum line, I use the line from the second air pump, since my car do nor have that pump....
can you send me a picture of were do you get your vacuum reading?

Picture shows what your charged air has to pass through to reach the runners of the manifold.

There is no provision for a vacuum reading post laminova's, unless you drill and tap a hole in the manifold.

Does anyone have HP numbers to support these camshaft combo? Overlap is not recommended for SC. Why would you have more on your intake side than your exhaust side? The air is being compressed (multiplied) in, so it would be more beneficial to move the air out of the engine more quickly. I am aware that things that make sense don't always work, but we never have seem to have reports on actual hp gains from the cams...
